Musician Jack Brown thought his song “The Road to Happy” wouldn’t be meaningful to anyone but him.

But now, a song about a bike ride in West Texas is the most popular in the Idaho-based singer’s repertoire and the centerpiece of a fundraiser Sunday for Amarillo’s Share the Road! organization.

Brown, who splits his time between bicycling, teaching music, singing and songwriting, wrote “The Road to Happy” a few years ago after a trip to visit friends in Canyon.

“I thought then, ‘What a great idea for a song.’ That was wintertime, but I came back in the summer and did a bike ride there. The song came together after that,” Brown said.

The song is part metaphorical, part a specific recounting of a bike trip between Amarillo and Happy.

“Happy’s not a frown turned upside down; it’s more than just another Panhandle town,” the chorus goes. “It’s a journey, not a destination.”

But one particular line strikes home for Share the Road! supporters.

“Some say the highway’s a barren waste, nothing to do or see,” Brown sings, “so they drive real fast and they phone their friends ’cuz they don’t have time and they’re in a hurry.”

That’s reflective of the incident that inspired the formation of the advocacy group: the 2010 death of Amarillo rider Cindy Whitney on that stretch of highway.

Brown was touched by accounts of Whitney’s death and offered his services to the advocacy group.

He’ll perform Sunday at the Amarillo Botanical Gardens in a benefit concert for the organization.

“All of the ticket proceeds go to us,” Share the Road! president Ken Graham said. “That’s the way Jack wanted to set it up, and we were delighted to accept his offer.”

Concertgoers are asked to bring lawn chairs or picnic blankets and are allowed to provide their own refreshments, Graham said.

Brown said Share the Road!’s mission resonates with him.

“As an avid road cyclist myself, that’s nearly happened to me a couple of times. ... I want people to understand that we who ride bikes love to share the road, too. ... We can all learn to get along, to use what’s become a cliche.”
